PWC and jet ski lifts in Miami Beach

Who this is for

Owners with one or two jet skis or a small tender who want them out of the water and easy to launch.

Narrow island canals and the 25% rule

On the narrower Miami Beach canals, DERM's short form allows a dock, lift or davit to reach no more than 25% of the waterway width. DERM also uses a D-5 boundary to protect a neighbour's view and access, so it may ask for a letter of consent from the lot next door.

That rule decides whether a floating, drive-on or seawall-mounted PWC lift fits.[1]

Tide at Government Cut

NOAA's Miami Harbor Entrance gauge at Government Cut, beside South Beach, shows a 2.46 ft mean range and a 2.70 ft great diurnal range, with mean higher high water about 0.33 ft above NAVD 88 (1983 to 2001 epoch). A wall at 5.7 ft NAVD therefore stands roughly 5.4 ft above an average high tide, the margin the City wants for king tides and sea level rise.

The tide range sets how high a fixed PWC lift has to raise the craft.[2]

Bay-side lots and the aquatic preserve

Lots that face open Biscayne Bay rather than a dredged canal sit on the Biscayne Bay Aquatic Preserve, which counts as Outstanding Florida Waters. There the state dock exemption is 500 sq ft of over-water area, and the preserve says manatees move into the bay in the cooler months.

Floating lifts shade the bottom, so they stay off grass.[3][4][5]

What makes Miami Beach different

The city has about 55 miles of seawall, of which only about 5 miles are publicly owned, so most of it is the responsibility of private owners. Its seawall ordinance dates from Resolution R2016-4009 in May 2016, was strengthened in January 2021 and amended again in July 2025.[6][8]

Groundwater and flooding

The city notes that groundwater rises through the porous bedrock under Miami Beach, so a seawall alone cannot stop flooding. A raised wall stops tidal overtopping; drainage and flood protection handle the rest.[9]

Permits in Miami Beach

• City of Miami Beach Building Department: Building permit with a site plan, structural plans and an elevation certification.
• Miami-Dade DERM, Coastal Resources Section: Class I permit or exemption for seawalls, docks and lifts on the island canals and the bay, issued alongside the City permit. Phone (305) 372-6575.
• Florida DEP or South Florida Water Management District: State review where a dock or wall reaches open Biscayne Bay, part of the aquatic preserve, where FDEP's free online self-certification is not available.
• US Army Corps of Engineers, Jacksonville District: Federal authorisation for work in Biscayne Bay and Indian Creek; we confirm the small-project route since SPGP VI's stated July 2026 expiry.

Floating or fixed?

Floating drive-on lifts need no pilings and suit most canals. Fixed lifts and davits suit spots with strong wakes or where floats would ground at low tide. Floating lifts count toward the 500 sq ft state exemption together with any floating platform.[4]
